The sockets api provides many configuration options so we will try and cover the socket api components and then give examples of a few implementations. The environment, resource limits, umask, controlling terminal, current working directory, root directory, signal masks and other process resources are also duplicated from the parent in the forked child process. Accept the first connection request on the queue of pending connections, create a new connected socket with mostly the same properties as defined by the call to socket(), and allocate a new file descriptor for the socket, which is returned.

. This tutorial will cover the creation of child processes and process control using fork, exec and other c library function calls using the gnu c compileron the linux operating system.
